Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already cover readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the description does not need to repeat safety traits. It adds the catalog-browse behavior, the returned fields, and pagination via offset, which is useful context beyond annotations. It does not go further into limits or other edge behaviors.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is short and front-loaded with what the tool does and returns. The sentence about add_to_cart is slightly tangential but brief and helpful for workflow context. No wasted words overall.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple read-only listing tool with no required parameters, a full output schema, and complete parameter documentation in the schema, the description is adequate. It tells the agent what is returned and how to page. It could have noted the relationship to search_products or best_sellers, but that gap is more about usage guidance than completeness.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%: both limit and offset are already clearly documented. The description only restates the offset paging concept, so it adds no significant semantic value beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource: it lists products in the store, enumerating the fields returned (title, price, sale price, availability, image, URL). It does not explicitly distinguish itself from siblings like get_product, search_products, or best_sellers, but the catalog-browse framing gives some differentiation.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description conveys that this is for browsing the catalog and mentions paging with offset, which implies usage context. However, it does not explicitly state when to prefer this over search_products, get_product, best_sellers, or related_products, and provides no exclusion criteria.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
